Fixing simultaneous use of aggregated units and maintenance breaks

See merge request !22

Updated result tables: changing r_gen_gnUnittype renamed to r_gnuTotalGen_unittype, changing sum over gnu_output to gnu in three tables. See changelog.

This helps in special cases where no. scenarios has been defined to some nonzero number
to allow moving the samples along with the dispatch. See changes to inc/3b_periodicLoop.gms in b6030656.

Adding new result tables: r_balanceMarginalAverage, r_resDemandMarginalAverage, r_gnTotalReserve, r_gnnTotalResTransferRightward, r_gnnTotalResTransferLeftward

Solver might terminate normally (solvestat = 1) even when the model is found infeasible.

- Removed outdated workflow items
- Created json and sqlite templates for the database and added to the workflow

- Storing constant and timeseries form reserve demand in the same parameter

- Deleting constant alternative names from importer mappings
- Importing timeseries form of unit efficiency data into a separate parameter efficiency_ts and similar update to the exporter

This can be used in non-anticipativity constraint equations to speed up equation creation for the model.

Fix `storageValueUseTimeseries` not exporting to `p_gn` as in da2665c9

Replacing relationship classes restype_released_for_realization, restype_inertia, and unit_fail with parameters that have value 1 if the objects should be included in the corresponding Backbone sets

- Adding other efficiency curve related parameters for units in the `efficiency` Map
- Renaming input_output object class to io
- Renaming restype__direction relationship class to restype__up_down
- Renaming effLevel__group__unit relationship class to effLevel__effSelector__unit
- Moving boundary data from grid__node to grid__node__boundary
- Including p_groupPolicyUnit data in unit__group instead of creating a new group__unit relationship class
- Deleting commodity mappings
- Including ts_priceChange data in node
